Due to global climate changes and increase in the speed and scale of anthropogenic loads, the need for plants with increased resistance to various stressors for conserving and restoring forest genetic resources increases annually. Poplar (Populus L.) refers to species characterized by early maturity, rapid growth and ecological plasticity, which contributes to solving these issues aiming to increase productivity and growing terms of forest plantations. This paper presents the experiment carried out in order to study the response of poplar, taken from the collection of long-term storage in vitro, to a simulated stress - salinity (NaCl), as one of the most common abiotic stresses. It was found that all the clones involved in the experiment were susceptible to the given stress factor. The interclonal and intraclonal variability of poplar in relation to the stressor is shown.
